The invention discloses a radio frequency excitation response measurement device and a transfer function measurement system, which are suitable for a linear configuration test piece, wherein the measurement device comprises: a base for fixedly mounting the test piece; an excitation input portion, fixedly installed on the base and electrically connected with the test piece; a moving portion installed on the base and capable of moving along the length direction of the test piece, wherein a measurement coil is installed on the moving portion, and the measurement coil is arranged on the test piecein a sleeving manner; and a response output portion electrically connected with the measurement coil. By applying radio frequency excitation to the tip of the test piece, the excitation response at each location of the test piece is measured by the measurement coil along the test piece so as to calculate a transfer function of the test piece. Therefore, an implant and a human body model can be decoupled by using the tran
